A 'conrom'rioiv or nanawaaia snai` srnINe.

To all whom t may concern:

Be it known that I, CHARLES F.' GREEN, a citizen of the United States, residing at Defiance, county of Defiance, and State Vof Ohio, have invented certain new and useful Im rovements in Seat Springs, of which I dec are the. following to be a full, clear, and exact description. A

This invention relates to cushion seats and has more particular reference to the means employed for quickly and permanently attaching the skirt of the cushion seat to the seat spring or the frame enclosed thereby. An object of the invention is to provide a articularly efiicient means for clamping the ower edge of the cushion skirtbetween a plurality of plates to securely bind the plates to the lower edge of the. skirt; one or both of said plates being provided with means whereby the strip may be secured to and su port the spring frame.

lFurtherobjects of this invention are to provide a means of the character indicated which will particularly facilitate the'quick assembling and' permanently attaching of the parts. Moreover, it is an object of the invention: to provide on.` the exterior lower edge of the cushion skirt va continuous, `un-1 broken metal protecting edge, which will have the advantage-of reinforcing the lower edge of the skirt and preventing wearing of the saine due to contact with lthe frame of the motor vehicle or other structure upon which the cushioned seat is used.

Further objects of the invention relate to economies of manufacture and details of construction as will hereinafter appear from thendetailed description to follow. I accomplish the objects of my invention in one instance by the means and devices described in the following specification, .but it' is evident that the ysaine may be widely varied without departing from the scope of the invention as pointedout in the appended claims. A structure embod ing one form of my invention,

which may the preferred, is illustrated in the accompanying drawings, forming a part hereof, in which:

lFigure I is a vertical transverse sectional view of the cushioned seat and my improved. attaching means illustrated therein.

Figure II is a longitudinal sectional vie'w taken on the line II-II of Figure I.

Figure III. represents a perspective view of one of the parts of the plate for securing Specification of Letters Patent.

Figure V is a perspective view showing the strip assembled to the cushioned skirt and .to a portion of the spring frame unit.

Figure VI is a sectional view taken on the line VI--VI of Figure II.

Referring to the drawings, the upholstered and fabric portion of, the improved spring cushioned seat is illustrated at 10 as includ ing an upward upholstered portion 11, and a depending skirt portion 12 secured to the portion 11 in any convenient manner as, for 70 exai'nple, by the bead 13. The skirt portion 12 is adapted to enclose the spring frame and springs of tliecushioned seat and is also provided adjacent the -lower edge thereof with means for securely attaching the skirt to the spring frame and supporting the frame in the assembled cushioned seat. My present invention is particularly concerned with the last mentioned means and one embodiment thereof is illustrated in the drawings. A feature of the invention isthe provision of two co-acting plates for binding the lower edge of the skirt 12 in clamping relation between the two, and also forming means for securing the same to the spring frame and supporting the spring frame properly within the cushioned seat, the construction being such that the same may be readily assembled by temporarily locking or hooking the frame in the plate sections referred to and then thereafter permanently locking or hooking the two together.

To these ends I have, provided an inner I plate 15, a portion of which is illustrated in Figure III, the saine having an upright ver- .tical fiange 16, a beaded angular edge 17 with a reverse U-shaped bend 18 extending` inwardly from the outside face of plate 15, the U-shaped ortion terminating in an inwardly extending flange 19. The U-shaped 4portion 18 of the plate is adapted to form a recess within which the lower -edge of the skirt 12, which may include a bead 12', may be located. Plate 15 is located inside the Skirt '12, while co-o eratiiig therewith is a 106 binding and attaching late 20, shown in Figure IV, adapted to bind the skirt 12 be` tween the same and the plate 151as shown in Figure V. One suitable form of plate 20 is to provide the'main portion thereof with 110 Patented May 9,1922. VApplication filed November 18, 1918. Serial No. 262,991. l

plate 15. The inner efge of lthe plate 20 may also be rovidedwith an upturned reversely bent Y ange 22 adapted to be clamped upon the inwardl extending flange 19 of the first mentione plate. The flange 22 of the plate 20 may be cutat intervals on the line 2?) to form the upwardly reversed ears or hooks 24, which may be used as means to clamp theplates 15 and 20 to the spring unit or its frame, as, for example, to the border Wire 25 thereof. Any number of ears 24 may be provided at any desired po1nt around 4the peripheral edge of the plate 20, as will be ap arent from inspection of Figure II.

The p ate 2O may extend entirelyI around the perimeter of the seat, while t eplates 15 may extend across one side only, 1f desired.

From the structure described it will be apparent that the lower edge of the skirt 12 v with the bead 12 may be clamped between the plates 15 and 20 by positioning the plates inside the skirt 12 with the bead l2 within the U-shaped recess 18, after lthe co-acting late 20 had been placed around the seat. lI'he strip 12 will then be clamped between the outcurled edge 21 of the strip 20 and the bead 17 of the strip 15, while the flange 22 of plate 20 is clamped down on to the inwardly extending portion 19 of plate 15.

`With this metallic strip unit secured to the lower edge of the skirt 12,the parts may then be assembled to form the complete spring cushion seat after the spring unit with the frame thereof have been disposed within the skirt 12. The border wire 25 temporarily hooked under the ears 24 and in this way the frame for/the spring is first temporarily attached to the supporting strips on the skirt 12. Thereafter, by the use of any Suitable implements the hooks 24 may be clamped down to permanently fix the plates with the wire '25.

The co-acting plates 15 and 20 form particularly efficient and stiffening means for joining the parts of the cushioned seat referred to, and it will be noted that there is formed by the curled portion 21 of the plate 2O a continuous strip of metal extendingentirely around the lower peripheral exposed edge of the skirt 12 to protect the same from wear as the cushioned seat is applied to and removed from the frame within which the seat is normally placed when in use. By /the use of the plates 20 and 15 arranged in substantially the manner described, a particularly strong frame for the skirt is pro- 60 vided which is capable of withstanding various strains to which the-entire device may be subjected. It is further noted that the lower edge of the. skirt 12 is clamped between the plates 15 and 20 by a continuously extending portion of each of the plates,

liable to tear the fabric or otherwise injure the skirt portion of the cushioned seat.

While I have described my invention in more or less detail, as being embodied in eertain forms, I do not desire or intend to be limited thereto since, on the contrary, my invention contemplates broadly all proper changes in thel form, construction and arrangement of the parts, as well as the omission of imma-teria elements, and the substi-`V tution of equivalentsy therefor as circumstances may suggest, or necessity render expedient.
